Cohesive stretch-tape wrapper with positive-braking action

Abstract

The wrapper includes a roll of stretch-tape on a central core, in its basic form, with a single end extension. A cap is secured at the remote end of the extension, and an incompressible sheath encircles the extension to freely rotate when the wrapper is used with tape being drawn from off the roll. The cap is dimensioned to prevent the sheath from separating from the extension, and is grasped by the heel of the hand of the user to prevent rotation of the extension when the tape is stretched, to be broken from the roll. Because the cap is of greater dimension than the sheath, the wrapper can be hand-held and operated at any angle as the circumstances of use dictate. In a second version, a pair of end extensions can be employed, making the use two-handed instead of one-handed, with the same type of braking action being provided by the caps being grasped by the heels of the hands of the user at either end preventing rotation of the stretch-tape roll.

I claim: 
     
       1. A stretch-tape wrapper comprising: a roll of stretch-tape on a central core and rotatable therewith;   a co-linear extension coupling with said core only at one end thereof;   an incompressible sheath surrounding said co-linear extension along a portion of its length; and   means situated at said end of said co-linear extension remote from said roll of stretch-tape for preventing separation of said incompressible sheath from surrounding said co-linear extension during periods of use of said stretch-tape wrapper at all extending angles of use;   wherein said roll of stretch-tape is located along said central core at an end thereof remote from said co-linear extension;   wherein said incompressible sheath is open at the opposite ends thereof and of a length less than the length of said co-linear extension;   wherein the inner diameter of said incompressible sheath is greater than the outer diameter of said co-linear extension in permitting the free rotation of said co-linear extension within said sheath when said wrapper is in use;   wherein said means includes a cap at said end of said co-linear extension having an inner diameter just slightly larger than the outer diameter of said co-linear extension to form a snug-fit therebetween and an outer diameter larger than the outer diameter of said incompressible sheath;   and wherein the lengths of said co-linear extension, said incompressible sheath and said cap are selected to permit a user to grasp with one hand both said incompressible sheath and said cap at the same time, with the heel of the hand grasping said cap;   whereby said incompressible sheath is captured in movement along said co-linear extension from said roll of stretch-tape to said cap in all angles of use of said wrapper, in unrolling said stretch-tape from said roll when not imparting pressure to said cap by the heel of the user's hand, and in breaking said stretch-tape from said roll when imparting pressure to said cap by the heel of the user's hand.   
     
     
       2. The wrapper of claim 1 wherein said roll of stretch-tape is of a width equal to, or less than, the length of said co-linear extension. 
     
     
       3. The wrapper of claim 1 wherein said co-linear extension is provided as an integral part of said core on said roll of stretch-tape. 
     
     
       4. The wrapper of claim 1 wherein said co-linear extension is provided as part of a separate dispenser arranged to couple within said core of said roll of stretch-tape. 
     
     
       5. The wrapper of claim 1 wherein said roll of stretch-tape is of a width greater than the length of said co-linear extention. 
     
     
       6. A stretch-tape wrapper comprising: a roll of stretch-tape on a central core;   a co-linear extension of length L 1  coupling with said core, and having an outer diameter D 1  ;   an incompressible sheath on said co-linear extension, having a length L 2 , an inner diameter D 2  greater than the outer diameter D 1  of said co-linear extension, and having an outer diameter D 3  ;   a cap on said co-linear extension at an end remote from said roll of stretch-tape, having a length L 3 , an inner diameter D 4  slightly larger than the outer diameter D 1  of said co-linear extension so as to provide a snug-fit therebetween and an outer diameter D 5  larger than the outer diameter D 3  of said incompressible sheath;   wherein the co-linear extension length L 1  is greater than the sum of the incompressible sheath length L 2  and the cap length L 3  taken together; and   wherein the co-linear extension length L 1  is selected to permit a user to grasp both of said incompressible sheath and said cap at the same time with one hand, with the heel of the hand grasping said cap.
